UNIVERSAL JOINT.

To all ii /tom it may concern Be it known that I, nniuins E. Pnnnms, acitizen of the llmted States, residing at Grand Rapids, in the county ofKent and State of Michigan, have invented new and useful Improvements inl'niversalkloints, of which the following is a specification.

The present invention relates to universal I joints, such as areemployed to connect rotatable shafts not alined; and its object is toprovide such a joint which shall be simple, and economical inconstruction; and

- further, such a joint Whose parts may be easily assembled anddisassembled. This, and any other objects liereafter appearin areattained by, and the invention finds preferable embodiment in thestructure hereinafter described and illustrated by the accompanyingdrawings, in which I Figure 'l is aview, principally in axial section,of a-universal joint; Fig. 2 is a transverse section of the same takenon a plane corresponding to line A-B of Fig. 1, the connecting membernot being sectioned and the nut being removed; Fig. 3 is a plan view ofthe connecting member with its nut; and, Fig. 4 is aside view of thesame (the nut being shown in position ready to be screwed down), partlyin section on a plane corresponding to line CD of Fig. 3.

The shaft members 1, 2 (either of which may be the driven shaft) areconnected by the connecting member 3 and the parts carried thereby. Thisconnecting member has angularly disposed intersecting open sockets 1, 5adapted to snugly receive respectively the spindles 6, 7 Which arehalved at 8, 9 in their middle portions, in order to receive each other.The end portions of the respective spindles rock in the rock bearings10, 11 of the shaft members, which bearings, as shown, have the bushings12, 13. The connecting member is threaded as at 1%, on which threads thenut 15 threaded as at'16 may be turned so that when screwed down (as byapplying a wrench to the squared portion 17) on the spindles in thesockets, such spindles are tightly and securely held by the nut in suchsockets. The connecting member, as shown, has lugs 18 around or outsidewhich .the annular rib 19 of the nut engages when screwed down, in orderto strengthen the parts. It will be seen that when the nut is screwedoff, the spindles may be separated and also the shaft members. it willalso be seen that the spindles are insorted-into and removable fromtheir sockets in a lateral direction.

The invention being intended to be defined solely by the claims, is notto be limited to or by details 01" construction shown or described.

I claim:

1. In a universal joint; shaft members having rock bearings; a threadedconnecting member therefor having open sockets ahgularly disposed;spindles adapted to be laterally-removably held in the sockets and Irocking in said bearing anu a nut threaded on the connecting membersthreads and adapted to hold the spindles tightly in the sockets. i

2. In a universal joint; shaft members having rock bearings; a threadedconnecting member therefor having" open sockets angularly disposed, andlugs; and a nut thriaded .on the connecting members threads and adaptedto hold the spindles tightly in the sockets, and having an annular ribadapted to engage outside the lugs.

In a universal joint; shaft members having rock bearings; a threadedconnecting member therefor having open sockets angularly disposed;spindles halved in their middle portions to receive each other, andadapted to be latei'ally-removably held in the sockets, and rocking insaid bearings; and a nut threaded on the connecting members threads andadapted to hold the spindles tightly in the sockets.

4. In a universal joint;shaft members having rock bearings; a threadedconnecting member therefor having intersecting opt sockets angularlydisposed; spindles halv a; in their middle portions to receive e other,and adapted to be laterallymenrov ably held in the sockets, and rockingl bearings; and a nut threaded on the cor necting members threads andadap': to

. hold the spindles tightly in the sockets.

In testimony whereof I have herei ito set my hand in presence of twosubscribing witnesses at Grand Rapids, Michigan, this 101 1 day ofOctober, 13.. 1916. a
